PS9, Line 9: This has the added benefit of cutting down one some
           : pre-processor usage as suggested by Angel Pons as the
           : function is always defined.
I find this a bit confusing. Suggestion:

As suggested by Angel Pons, add the function `is_internal_programmer`
  and cut down some pre-processor usage by moving them into that new
  function.
  <empty>
  The function checks if the internal programmer is the
  selected one. If the internal programmer is not built in, then it
  returns just false.
